Hypothetical but that's not normally the case. Where has that happened in recent history? I don't disagree that the team is in bad shape but teams normally blame the coach and the GM.
Loomis has to get his HC hire right or his job and his legacy are gone. He is going to give Moore every opportunity to succeed for as long as he can pull it off. And that means until the fans have so turned on Moore that Mrs. Benson has to step in and fire him personally.
Loomis has bet his job and legacy in the NFL on Moore. If he hits, then Loomis saves his legacy. If he tanks, then Loomis is thought of as a failed GM that got lucky one time and he loses his job.
